ELECTRIC swiToHfBo'x.

Be it known that I, WILLIAM R. AT-KINsoN,

a citiap n of the United States, and residing at ork,.in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Electric .which the following is a use the same.

This invention relates to electric switch boxes for use in connectionwith wall switches, and the object thereof is to provide an improveddevice of this class designed for use in connection with flush wallswitches a fur? ther object being to provide an improved device of theclass described, the construction of which is such as to'facilitate theinstallationof electric cables for electric lights and similar purposeswhereby. the insertion of the "cables into the switch box and thelocking of views, and in which said cables in said box is facilitated.

The invention is fully disclosed in the following specification, ofwhich the accomp anying drawing forms a part,'iinwhich theseparate'parts of my improvement are designated by suitable referencecharacters in each of the Figure 1 is a perspective view of my improvedswitch box and showing the opposite sides thereof open; Fig. 2 a similarview of; one ofthe side plates of the box detached;

and, Fig. 3 a longitudinal central section 'throu h the complete box.

In t e practice of my invention, I'- provide a The box a is closedat oneend as shown at a and open at the other end and provided with projectinglugs 0 whereby it may be secured to a'wall construction in the usualmanner.

The open end ofthe box is also provided with the usual lugs orprojections and screws a by f by which the plates 1) areheld inposition, and

means of which the switch plate or cover of the box is secured theretoas usual with other devices of this class.

The opposite sides of the box a are open as shown at if, and said opensides are closed, in practice, by plates 12. the box a are provide. withlongitudinally arranged angular shaped keepers 0 between which and theopen sides of the box the plates 1) are inserted, and said plates 7) areprovided at the inner ends thereof with angular-projections 6 throughwhich are passed screws cl Specification of Letters Patent. i

end with inwardly directed/flanges or side. ()5

members we provided with segmental recesses e 'The corresponding ends ofthe plates 6 are provided with similar recesses c and when .theplates 1) are inserted into position as shown in Fig. 3, the recesses eand e form circular openin s in the opposite sides of the box through wicli electric cables f may be passed as indicated in dotted lines inFig. 3,

Electric switch boxes of this class are usually rovided in the oppositesides thereof with oles intO'Wl'llOll' the cablesa're passed, buttheseholes are small and it isvery difiicult in a wall construction ofthe class described to get the cablesinto the boxes, but

with my improvement, in,whi ch the opposite side portibns of the boxesare made separate and removable there is comparatively no troublewhatever ofthis kind as the elec-' tric cables can be easily passed intoopen sides of the boxes, and the separately formed .side members of thebox may then be inserted and secured in position, and in this operationthe cables are forced back into the openings formed by the recesses eand as here'inbefor'e described, and it will be un'der- 9o stood thatany desired number of said open ings may be employed, and one or more ofsaid openings may be closed when not desired for use in the manner ofother devices of this class. 1 also be used in all kinds or classes ofwall construction the same as other devices of this class, or wherevertheguse of such devices is required, the only difference between my Myimproved switch box mav improved electric light switch box and others ofthis class being in the f-act'that the opposite side portions of thebox'are formed separate and detachably connected therewith in the mannerdescribed, the hole'sthrough which the electric cables are insertedbeing 10 5 formed in the end part of the detachable side portions of thebox, or partly in said detach-- able side parts of thebox, and partly inthe permanent side members of the box in connection with whichthedetachable side tions of the box are employed. Having fully describedmy invention, wh at ractice, is closed-bypaand cover p ate hereinbeiore.r'e-j POT- I [O I-claim as new and desire to secure by ters-l atent,is:4 I
